SPECIFICATION" forming part of Letters'Patent No. 547,449, dated October8, 1895.

Application and April s, 1895.

To all whom it may concern/.-

Be it known that we, EDWIN H. POWERS and EUGENE A. TELEAIR, citizens ofthe United States, residing at Michigan City, in the county of La Porteand State of Indiana,

have invented certain new and useful Im-A ducing the diagonal strandinto the cane lfabric used particularly in the manufacture of` the seatsof chairs, its object being to secure the rapid introduction of suchstrands in a` uniform manner and by means of an automatic machine ofsimple construction.

The invention consists of a shuttle having a spiral pirn, to which iscommunicated a positive rotary motion, and which draws the strand intothe interstices of the fabric.

It consists, further, of means for measuring off and cutting the strandsinto suitable lengths and automatically attaching them to the pirn.

It consists, further, in-means for reversing the shuttle, so that itoperates in both directions. A i

It consists, further, in various features and details of constructionaccessorylto the several principal features above enumerated.'

The standrof the machine is a rectangular frame 1, and may beconstructed of gas-pipe, as shown. The fabric to be operated upon isshown at 2 as `it is being passed through the machine and at 2a as itleaves the machine, withone set of the diagonal strands introduced. Thefabric is fed tothe machine from a spool (not shown) mounted upon arectangular shaft 3, carried by blocks 3c 3d, secured to' two of the endlegs of the frame. llt is passed upwardlyand over aro1ler3b,journaled ina pair of arms extending upwardly from the end of the frame, and then,being carried the length of the frame, passes between a pair offeed-rollers 4 4, to which an intermittent motion is communicated, aswill be hereinafter described, and is thenf wound upon a spool 1lb,journaled in blocks secured tothe two legs at the opposite end ofthetable from that at which the feed-spool is located. The shaft 3a isremovably clamped between the blocks 3e 3f, the former of which is fixedin a socket in the block 3c by means of a set-screw 3S, and has a stud3h for the engagement of a socketin the end of the shaft 3", While thelatter is journaled' in theblock 3d and has a rectangular socket for thereception of the end of the shaft. The block Sfis permanently set withinits bearing. Vrlhe Ashaft 3a is removed from theframe for changingspools by loosening the set-screw 3g, when theblock 3 will slide back inits bearing, releasing the haft. The block 3f hasv at itsinner end ahead to prevent it from sliding in its bearing to release the shaft, andupon the opposite end are mounted a fixed collar 3J', aleather washer3k, and a loose metal washer 3m. The

outer end of the block 3f has a screw-threaded ICO ' 3m against thewasher 3k.

socket, into which is set a screw 3P, which carries a spiral spring 3,which forces the washer The washer 3m is notched for the engagement ofthe catch 3f, fixed to the post of the frame 1, and is thereby preventedfrom rotating. The friction between the washer 3k and 3m, or between theformer and the collar 35, prevents the too rapid feeding of the fabricfrom the spool.

The head of the machine is supported by a frame 21, comprising uprightssecured to opposite sides ot' the frame and a cross-bar uniting theirupper ends. This frame 21 is diagonal to the frame 1, and to it aresecured horizontal slide-bars, upon which are mounted theshuttle-carriers. The shuttle consists of the upper and lower members 99, between which the fabric to be operated upon is carried.

The pirn for carrying the diagonal strand into the fabric is carried bythe shuttle by being` clamped between its two members, is spiral inform, and runs through the fabric, as will be hereinafter described.This pirn is shown at 5 and is made of a round steel rod worked to aspiral form with a pitch to correspond with the mesh of the fabric. Itsforward end is pointed that it may more easily find its way through thefabric. It is provided with a central backwardly-projecting stem 5, towhich is swiveled a tailpiece 6, having a lateral recess 6l for engagingand holding the strand. The attachment of the tailpiece to the stem isaccomplished by providing the latter with a shank b, having an annulargroove 5 and socketing the end of the tailpiece to fit this shank. Thetailpiece has a transverse aperture adapted to register with the grooveand in this is fitted a pin 6, which, entering the groove 5, holds thetailpiece 6 upon lthe shank 5, but allows it to turn freely. The pirn isgiven a positive rotary motion by the cam action of a pair of notchedplates 8 8, located between the two members of the shuttle, theirnotches S being cf such size and location as to engage the severalconvolutions of the pirn.

The plates 8 8 are supported by plates 3, extending between the uprightsof the frame 2l, and supported, also, by posts S, standing up from aplate 8, secured to the top of the frame 1. r1`he shuttle comprises thetwo blocks 9 9, the one above and the other below the plates 3 S. rThefaces of these blocks are beveled at their forward ends that they mayadvance more smoothly and are centrally recessed. lVithin the recess ofeach block is journaled a pair of antifriction -rollers 15, which bearagainst the pirn. Bearing or wear plates 9b 9c are secured to therearward ends of the blocks 9 9, closing their central re cesses andforming internal bearing-surfaces for such blocks. These plates projectbeyond the faces of the blocks, their adjacent edges being spaced apartonly sufficient to clear the plates S S. The pirn is carried forward bythe wear-plates 9b 9c bearing againstits rearward end, which is radiallyflattened to make a bearing-surface of considerable area, so that as thepirn is turned by running in the notches 8 1 its flattened end slidesupon the inner faces of the plates 9b 9c and does not leave one of themuntil after it has engaged the other.

The shuttle-blocks 9 9 are carried by slideblocks 1S 19, to which theyare secured by means of trunnions 9 and 16. Wear-blocks 1S 19 areinterposed between the blocks 18 and 9 and 19 and 9 and are preferablyof brass.

The blocks 18 19 are apertured to slide upon rectangular bars 2() 20,set in the upright members of the frame 21, and are united by means of aU-shaped frame 10, whose arms are of sufficient length so that its bowor transverse portion 10 always extends beyond the end of thesupporting-frame 2l. The bars 2O 2O are also prolonged beyond thisframe, and the frame 10 has at its outer end loops 10h 10b, adapted toslide upon these bars.

The shuttle is caused to reciprocate by means of a sprocket-chain 11,carried by horizontal sprocket-wheels 12 12, located below the plate Sb.Motion is communicated to the machine by means of a4 drive-pulley 13,mounted upon a shaft 13, journaled in suitable blocks carried by thelower portion of the frame 1, and which carries, also, a beltpulley 13b,from which a belt 14 leads to a pulley 14, mounted upon the verticalshaft 14h, which carries the sprocket-wheel 12.

The sprocket-chain 11 has one of its links (shown in Fig. 17) providedwith an upwardly-projecting stud 11. A link-bar 17 is mounted upon thisstud and projects inwardly between the two turns of the chain and is inrigid connection by means ofthe set-screw 17 within the tr-unnion orarbor 16, rigidly attached to the shuttle-block 9, thereby communicatingthe motion of the chain to the shuttle and reversing the latter as thestudded link is turned around the sprocket-wheels. The block 9 is causedto turn with the block 9 by reason of the engagement of the pirn withthe friction-rolls 15 15 of the two blocks.

The notches 8 of the plates 8 8 terminate at the end of the travel ofthe shuttle, and the plates 8 S and Sb Sb are recessed, as shown, toadmit of the turning of the shuttle. As it turns the tailpiece 6 slidesover the surface of the plate 8, and is thus prevented from beingaccidentally turned.

The shuttle-block 9 is held in proper position during its movementacross the fabric by means of the latches 22 23, pivoted upon theopposite sides of the block 19 by means of a pin 24, upon which both arefixed. rThe latches 22 23 are adapted to be thrown down alternatelybelow the block 19 in front of the link-bar 17. The latch 22 is in theform of a. rock-lever. The latch 23 is in the form of a. swinginglever'. A slide-bar 25, having on opposite sides cam-notches 26 27,reciprocates through the block 19, bearing against the top of the latch23 and the lower side of the inlal ner end of thelatch 22. As theshuttle reaches the limits of its travel, the end of the bar 25 strikesthe vertical members of the frame 2l. and is thrust back iu itsbearingin the block 19, the cam-notches 26 27 shifting the latches 2223, so as to'raise the one which was in advance of the link-bar 17, andthus allow this bar to swing around as the'link to which it is attachedturns the sprocket-wheel, and to lower the one which was behind thelink-bar, so that it will be engaged by it as it starts upon its returnacross the fabric.

The spool 4b, upon which the fabric is rolled after being operated uponby the machine, is rotated by means of a belt 4d, leading from a pulley13c upon the shaft 13a to a pulley C upon the shaft carrying the spool,the pulleys 13C and 4C being differentiated in size, so as to secure thenecessary slow motion for the spool 4h. lt is necessary, however, thatthe movement of the fabric through the machine shall be intermittent, asit must be stationary while being operated upon by the shuttle. Thisintermittent motion is obtained by means of the feed-rollers et sa,between which the fabric is passed after leaving the head of themachine. The roller 4 is driven by means of a friction-clutch 4e, whichis of the same form as is used in connection with the strand-feed, asshown in Fig 16, which will be presently described. This clutch isincorporated into the hub of a crank-arm 4f, which is oscillated` bymeans ofa pitman 4g, leading from a crankpin set in a gear-Wheel et,journaledinasuitable bracket attached to the frame l and driven by agear-wheel 4J', mounted upon the shaft of the sprocket-wheel12a. Therollers 4 et are connected at one end by intermesh ing gears, as'shown.

The action of the clutch te is so timed by suitably proportioning thegears 4th 4j that the feed-rollers are actuated while the stud ll, bymeans of which the shuttle is connected with the sprocket-chain l1, isturning about either one of the wheels l2 12, so that the fabric isstationary while the shuttle is operating upon it', and is moved by thefeed-rollers while the shuttle is being turned or reversed. The lengthot' each step of the fabric feed is controlled by the pointof attachmentof the pitman lg to the crank-arm 4f, and as the cane fabric is madewith different sizes of mesh it is important that provision be made forvarying the feed. This is accomplished by making the connection betweenthe pitman 4g andthe crank-arm 4f of the pinand-slot form, as shown, andin order that the feed may be changed from the side of the machine thisconnection is controlled by a lever 4ck, pivoted upon the shaft of thespool 4b, its free arm bearing against the vertical l post la, forming apart of the frame l, and is transversely notched or serrated for thepurpose of increasing the friction and preventing the accidentalshifting of the arm 42k. The short arm of the lever 4k is connected withthe pitrnan 4g by means of a link 4P. lt is of advantage that thefeedmechanism be under easy control by the operator for the reason thatthe mesh of the fabric is apt to be irregular, so that the feed needs tobe varied a little from time to time.

The material for forming the strand 7 is fed to the machine from anydesired source of supply above, which we have not deemed it necessary toshow, and is fed to each side of the machine by means of a pair offrictionwheels 26 27, mounted upon and at each end of the frame 2l, thestrand 7 being carried downwardly between them, the `faces of the wheelsbeing knurled to increase the friction.

The wheel 27 is carried by a sleeve 27a, mounted upon a stud 27h, havingan eccentric stem 27e, which is journaled in a block 2l, mounted uponthe frame 2l. A crank-arm 27d is xed to the shaft 27c and its outer endis connected by means of a spring 279with the block 2la in such manneras to tend to draw the wheel 27 downwardly and toward the wheel 26,thereby adapting the feed mechanism to any irregularities in thematerial while insuring a grip of the strand however thin it may be.VThe wheel 26 is carried by a sleeve 26", mounted loosely upon a stud26C, set in the block 2l, and a two-channel drum 261L is mounted upon4the sleeve 26b and is provided with the roller friction-cluteh 26d,adapted to lock the drum and sleeve together for rotation in onedirection. At 26e is shown a spring for holding the roller 26d in suchposition in its race that it is instantly engaged when the drum turnsagainst it.

The drums 26a at opposite sides of the machine are united by cords 2828, each wound oppositely upon the two drums, both with reference toeach other and with reference to its own ends. The cord 28 is attachedto an arm 29, projecting upwardly from the shuttle--carrier, so that asthe shuttle travels it unwinds this cord from one of the drums and,winding the cord 2Sa onto the same drum, unwinds it from the drum at theopposite end, thereby winding the cord 28 onto that drum. The clutches26d are'so disposed that the wheels 26 are rotated so as to draw thestrand 7 downwardly and are motionless when the drums 26 turn in theopposite direction. The strand after passing between the wheels 26 27enters a guide-tube 30, which leads to a vertical aperture in areciprocating slide-bar 3l. This bar is carried in a socket 82, fromwhich it protrudes and within which it slides inthe post of the frame 2land is held within this socket by means of a bolt 32a, set in the frameand projecting into a longitudinal recess 31* in the side ot the bar,thisrecess being of sufficient length to allow of the reciprocation ofthe bar within the desired limits.

A spiral spring 32b is placed within the socket 32 behind the bar 3l andtends to expel the latter. The aperture of the bar 31 continues IOO IIO

the passage formed by the tube 30, but is contracted approximately tothe shape in crosssection of the strand 7. A blade 33 is fixed to theside of the postof the frame Qlimmediately below the socket 32, so as tocutoff the strand projecting through the aperture of the bar 3l when thelatter is forced into the socket.. A rod 34 projects in each directionfrom the shuttle-carrier 18 in the direction of its movement and isadapted for contact with the outer end of the bar 31 as theshuttle-carrier reaches the limit of its travel, thereby forcing the barwithin its socket and cutting off the strand 7, which has been fed down.'It is necessary that the strand thus cut off be held by some form ofclamping device until engaged by the tailpiece of the pirn. Themechanism provided for this purpose comprises rectangular rods 35 35,mounted, respectively, to slidein suitable apertures in the wear-blocks18a 19, parallel with the line of travel of the shuttle. These bars 3535a are provided at each end with rigidly attached andlaterally-projecting arms 36 36, the arms projecting in each instancetoward the plates S 8. A spiral spring 37 is mounted upon. each end ofeach of the bars, being interposed between its lateral arm and the blockby which it is carried and being normally under slight tension. At theouter end of each of the arms 36 36a there is a horizontal offset 36h,in each instance projecting across the slot between the plates S 3,within which the pirn 5 travels. The length of the bars 35 35a is suchthat their lateral arms 36 36'DL come into contact with the verticalportion of the frame 2l before the rod 34 actuates the shears, and theyare thereby forced backwardly through their bearings, the springs on theforward ends of these bars being compressed. This action securely clampsthe strand 7 between the offsets 36b of the arms 36 36 and the frame 2l,preventing it from falling when cut off by the shears. A recess 38 isformed in the inner face of the upright portion of the frame 2l toreceive the tailpiece 6 of the pirn 5 when the shuttle is reversed forits return movement. The recess 6b in the tailpiece 6 of the pirn is onthe forward side as the shuttle turns and automatically engages thestrand 7 as the shuttle is brought into its proper position. As theshuttle starts upon its next trip across the fabric the expandingsprings 37 hold the arms 36 36a firmly against the frame 2l, and in themeantime the tailpiece of the pirn has traveled with the shuttle anddoubled the strand as it has been drawn between the offsets36", so as tosecure a hrm grip upon it. The springs 37 having resumed their normaltension, the arms 36 36n leave the frame 2l and the strand 7 is free tobe drawn into the fabric by the shuttle. As indicated in Fig. 4, thefolded end '7a of the strand 7 is held by the off- Y set of the arm 36,thereby preventing the disen- The aperture in the block 18a, withinwhich the bar 35 is carried, opens to and slightly encroaches upon thesocket serving as the bearing for the trunnion 9e. This trunnion has itssurface cut by two transverse V-shaped recesses diametrically oppositeeach other and parallel with the longitudinal line of the block 9 andadapted to receive an angle of the bar 35. The bar 35 engages with therecess in the trunnion 9e, serving as a dog to hold the block 9 steadyas it advances. angle of the bar 35, which enters the recess of thetrunnion 9e, is provided with two recesses 9c 9, located upon oppositesides of the trunnion and at such distances therefrom that the movementof the bar 35 Within its hub by means of its contact with the frame 2lcauses one of these recesses 9c 9d to register with the trunnion-socket,thereby permitting the block 9 to be turned.

XVe are aware that a spiral needle and spiral path-nder or a so-calledshed-former for a straight needle have been used for introducing thediagonal strand into cane fabric, such implement or combination ofimplements being operated by a thrust and being necessarily of a lengthequaling the diagonal width of the fabric. Such constructionnecessitates the withdrawal of the needle after the fabric has beencrossed or it is necessary to draw this long needle throughthe fabricafter the tip of the spiral finder has reachedthe opposite side.

In using the term pirn we intend to distinguish from this long implementand mean thereby a short piece which travels entirely across the fabric,drawing the strand with it, so that when the pirn has once crossed thefabric the operation is complete, the pirn, as herein described,differing from the pirn of a shuttle us'ed in the weaving of textilesonly in that it does not carry a supply of the material to be paid outas it advances, but draws the strand after it through the mesh.

Ve believe we are the first to introduce the diagonal strand into canefabric by the use of a spiral pirn havinga central swiveled tail pieceor strand-holder for the attachment of the strand and rotated bymechanical means and that We are entitled to protection in themanufacture, use, and sale of such a device by Whatever mechanism thepirn is rotated.
